A remanufacturing method for a process cartridge detachably mountable to a main assembly of an electrophotographic image forming apparatus, includes (a) an end cover removing step of cutting a fixing portion between the second end cover and the drum frame and cutting a fixing portion between the second end cover and the developer frame, and removing the second end cover at the other longitudinal ends of the drum frame, the developing frame and the developer frame; (b) a drum shaft removing step of removing, at the other ends, a drum shaft rotatably supporting the electrophotographic photosensitive drum at the other ends; (c) a roller separating step of applying forced to the drum frame, the developing frame and the developer frame in directions crossing with a longitudinal direction of electrophotographic photosensitive drum so as to separate the electrophotographic photosensitive drum and the developing roller from each other; (d) a drum removing step of moving the electrophotographic photosensitive drum outwardly from the process cartridge at the other end of electrophotographic photosensitive drum, while keeping the forces applied to the drum frame, the developing frame and the developer frame, so that electrophotographic photosensitive drum is inclined, and then removing the electrophotographic photosensitive drum from the drum frame; (e) a drum mounting step of inserting one end of a new electrophotographic photosensitive drum having at one end a driving force receiving portion for receiving a driving force for rotating the electrophotographic photosensitive drum from the main assembly of the electrophotographic image forming apparatus when process cartridge is mounted to the main assembly of the electrophotographic image forming apparatus, such that driving force receiving portion is exposed outside the drum frame, and inserting the drum shaft at the other end from outside of the drum frame, thus mounting a new drum electrophotographic photosensitive drum to the drum frame; (f) a developer refilling step of opening a filling port provided in the developer accommodating portion, refilling the developer and then closing the filling port; and (g) an end cover mounting step of fixedly mounting a second end cover to the other longitudinal ends of the drum frame, the developing frame and the developer frame.
